In today’s fast-paced world, the travel industry is constantly evolving to meet the demands of travelers worldwide. One key aspect of this evolution is the integration of travel APIs (Application Programming Interfaces) into web applications, allowing developers to access and utilize powerful travel-related data and services. Amadeus, a leading provider of travel technology solutions, offers a robust set of APIs that can be seamlessly integrated into PHP applications, enabling developers to create innovative and feature-rich travel solutions. In this article, we will explore how to integrate Amadeus with PHP and leverage its capabilities to enhance your travel applications.

What is Amadeus API?

Before diving into the integration process, let’s briefly understand the Amadeus API. Amadeus provides a comprehensive set of APIs that cover various travel-related functionalities, including flight search and booking, hotel reservations, car rentals, and more. These APIs offer access to extensive travel data, allowing developers to retrieve information such as flight availability, pricing, seat maps, hotel details, and much more. By integrating Amadeus APIs into your PHP application, you can provide users with real-time travel data and enable them to book flights, hotels, and other travel services seamlessly.

Now we are going to setup Amadeus API in 5 simple steps

    1. Set up a PHP project
    2. Install Guzzle, an HTTP client library for PHP
    3. Obtain an API key from Amadeus
    4. Write PHP code to interact with the Amadeus API
    5. Display flight results and implement booking functionality

    Step 1: Set up a PHP project

    Create a new directory for your project and create an index.php file inside it.

    Step 2: Install Guzzle

    To make API requests, we’ll use Guzzle. Install it using Composer by running the following command in your project directory:

    composer require guzzlehttp/guzzle

    Step 3: Obtain an API key from Amadeus

    Sign up for an Amadeus developer account at and create a new API key for the “Self-Service APIs.”

    Step 4: Write PHP code to interact with the Amadeus API

    In your index.php file, add the following code:

    require 'vendor/autoload.php';
    use GuzzleHttp\Client;
    $amadeusApiKey = 'your_amadeus_api_key';
    $amadeusApiSecret = 'your_amadeus_api_secret';
    $client = new Client([
        'base_uri' => '',
    // Obtain an access token
    $response = $client->post('/v1/security/oauth2/token', [
        'form_params' => [
            'client_id' => $amadeusApiKey,
            'client_secret' => $amadeusApiSecret,
            'grant_type' => 'client_credentials',
    $accessToken = json_decode($response->getBody())->access_token;
    // Search for flights
    $response = $client->get('/v2/shopping/flight-offers', [
        'headers' => [
            'Authorization' => "Bearer {$accessToken}",
        'query' => [
            'originLocationCode' => 'SFO',
            'destinationLocationCode' => 'LAX',
            'departureDate' => '2023-06-01',
            'adults' => 1,
    $flightOffers = json_decode($response->getBody())->data;
    // Display flight results
    foreach ($flightOffers as $flightOffer) {
        // Display flight details and booking form
    // Implement booking functionality

    Replace 'your_amadeus_api_key' and 'your_amadeus_api_secret' with your actual API key and secret.

    Step 5: Display flight results and implement booking functionality

    In the foreach loop, you can display flight details and create a booking form for each flight. When a user submits the form, you can use the Amadeus API to create a booking.

    Keep in mind that this is just a starting point. You’ll need to customize the code to fit your specific requirements, handle errors, and create a user-friendly interface. Additionally, you may want to implement caching to avoid making unnecessary API calls and improve performance.
